Tree roots keep a tree healthy and upright. Most roots are found in the top 600mm of soil and often grow out further than the tree’s height. The majority of these roots are very fine; even close to a tree few will be thicker than a pencil. Most street tree roots grow under the footway but may also extend under the carriageway. If roots are damaged the tree may suffer irreversible harm and eventually die.

The statutory right of undertakers (utilities) to carry out works within the public highway in order to provide and maintain their apparatus dates from the mid- 19th century and is set out in the relevant utility industry primary legislation (see Volume 6 – ‘Legislation and Bibliography’).

The New Roads and Street works Act 1991 (NRSWA) as amended by the Traffic Management Act 2004 (TMA) requires all works promoters to notify or apply for permits for all works in the public highway. This legislation also promotes the need for improved planning and co-ordination of all works in the highway in order to reduce the impact of works on the road user and wider community.
